I'll stick with my Mac.

Over 3 years old, still moves like greased weasel pooh and runs XP in a virtual machine faster than my PC at work.

Laptop, 4 Gb RAM, twin core processor, 500 Gb, 256 Mb video memory - new fully functioning operating system (unlike Microsoft Windows that disables software, even if your computer has the hardware) that cost me £21.00 (retail) instead of a couple of hundred.

Few if any bugs, few if any viruses. It's a no-brainer. Expensive, yes - but you get what you pay for and it WORKS.

Go Mac!
